What Sabre A&D delivers

End-to-end industrial automation and digitalization engineering — from system architecture and software development through commissioning and operational support.

PLC & SCADA development
Software development and integration of PLC and SCADA/HMI systems for industrial processes, including DCS architectures for complex plant control. Experienced working with multiple automation vendors including Siemens, Rockwell Automation, and ANDRITZ Metris.
Advanced Process Control
Design and implementation of APC solutions including evaluation of existing processes and control systems, identification of improvement opportunities across hardware (instrumentation, sensors, equipment) and software (PID tuning, MPC, control narratives), and actionable recommendations to enhance plant performance.
System integration
Connecting automation layers — from field devices to supervisory systems — using industrial protocols such as OPC-UA, Modbus, Profinet, Ethernet/IP, and others. Particular focus on cross-vendor interoperability, integration with higher-level systems such as MES and historian platforms.
Commissioning & support
On-site and remote commissioning, FAT/SAT support, and control system verification across process industries. Debugging of process and control problems, both remotely and on-site as the situation requires.
Legacy system modernization
Assessment and upgrade of legacy automation platforms — improving reliability, maintainability, and enabling modern data connectivity and operational visibility.
Documentation & consulting
Technical documentation, process assessments, and engineering consulting across the full project lifecycle — from requirements through operational support. Training and hands-on support for engineers and plant operators.

About Robert

Founder & Lead Engineer
Čepin, Croatia
🇭🇷 Croatian  ·  🇬🇧 English

I founded Sabre A&D to deliver focused, senior-level automation and digitalization engineering without the overhead of a large consultancy. Every project is handled personally — from requirements definition and system architecture through to on-site commissioning and operational support.

My background spans DCS/PLC and SCADA software development and commissioning in the steelmaking industry across five continents, as well as advanced process control in the animal feed and pet food industry. I also work part-time as a teaching assistant in industrial automation at the Faculty of Electrical Engineering in Osijek.
